A Channel (manga)

Main characters

• Tōru Ichii (一井 透 (トオル))
• A short first year student who often has overly long sleeves. Due to her short and skinny stature, she often has trouble finding clothes that fit her. She has been friends with Run since kindergarten, often getting lonely when separated from her and threatening anyone who tries to make a move on her. She disliked Yūko at first, since her first impression of her was seeing her in a compromising situation with Run, and since then constantly teases her at every opportunity. She has a pet cat named Tansan (炭酸). Tooru is very fond of sweets, which her friends bribe her with.
• Run Momoki (百木 るん)
• A blonde second year student with a parakeet like hairstyle and Tōru's best friend. She is incredibly ditsy to the point that her friends often have to stop her from hurting herself in the process. She is very forgetful, even forgetting to wear her panties and bring her school stuff. Despite her qualities, she is very caring for Tooru and will try to help her when she's somewhat troubled.
• Nagisa "Nagi" Tennōji (天王寺 渚 (ナギ))
• She is a second year student and Run's classmate who sports pig-tails and glasses. She is often called by Run, Yūko, and Tōru by her nickname, Nagi. She is pretty intelligent and often makes quip remarks to her friends. She is sometimes conscious about her weight and hates extreme temperatures. She looks completely different when she lets her hair down and removes her glasses.
• Yūko Nishi (西 由宇子 (ユー子))
• A long haired second year student and Run's classmate. She is something of a scaredy-cat who often finds herself at the mercy of Tōru's teasing, usually because she is envious of her tall and well endowed figure. She speaks with a prominent Kansai accent.

Other characters

• Yutaka Imai (今井 豊 (ユタカ))
• A first year student and Tōru's classmate. She is a fan of Tōru and constantly tries to get friendly with her, much to Tōru's despair. She is very talkative and always takes the chance to get close to Tooru, but is always stopped by Miho.
• Miho Noyama (野山 美歩 (ミホ))
• A first year student and Yutaka's friend and classmate, who Yutaka affectionally calls Mipo-rin. She is also a fan of Tōru, though not quite to the extremes of Yutaka, and constantly tries to keep Yutaka from bothering Tōru too much. She works part-time as a maid in a cafe.
• Kimiko Kitō (鬼頭 紀美子)
• Tōru's homeroom teacher, who is obsessed with poetry. She is often quite motivated in the mornings, much to the dismay of the students, and doesn't get along too well with Satō.
• Taki Kamate (鎌手 多季)
• Run, Yūko and Nagi's homeroom teacher, who has a rather laid back attitude. She is often seen teaching sports classes.
• Sachiyo Satō (佐藤 幸世)
• The school's health teacher, who is actually rather weak himself. He appears to have a crush on Run and has an infatuation with her forehead.
• Keiko (ケイ子)
• Yūko's younger sister who is quite dedicated to her sister.
